This invention is directed to an improved electrical power distribution system that provides continuous access for inserting take-off devices and also high current capacity. This invention provides enhanced electrical contact between the busbars and the stabs on take-off devices. This invention provides firm contact pressure and large contact surface area and allows a take-off device to be inserted at almost any point along the track. A unique retainer fits in a slot in the insulating support in the channel enclosure at each end of each busbar. The retainers are secured to the insulating support and thereby retain the busbar within the slot in the support.
